IPS module setup on 5500-X series ASA

Colin Higgins

Since the 5500X series firewalls use a software IPS SSM that is set up differently from the old ones, I am a little confused on the initial setup.

Looking at this document

http://www.cisco.com/en/US/products/sw/secursw/ps2113/products_tech_note09186a0080bd5d03.shtml

we see a proposed setup for L3 management of the IPS

------

interface GigabitEthernet0/0
 nameif outside security-level 0
 ip address 203.0.113.1 255.255.0.0
!!interface GigabitEthernet0/1
 nameif inside security-level 0
 ip address 198.51.100.1 255.255.255.0
!!interface Management0/0
 no nameif security-level 0

!!same-security-traffic permit inter-interface
same-security-traffic permit intra-interface

object network ASA-outside

   any
 
nat (inside,outside) source dynamic IPS-management IPS-management interface
 
nat (inside,outside) static IPS-management ASA-outside service tcp 443 65432

So my question is:

Where does the IPS module get the 192.51.100.2 address? Is this assigned during the initial setup of the module?
(I didn't see anything about IP assignment in

When you run the "setup" command from the CLI, one of the menu choices will be to assign the IPS Management address.

You can also do this from the ASA by using the Device setup wizard in the Configuration window. Just tell it to modify your existing configuration and click through the first several screens that pertain to the parent ASA until you get to the last couple that are IPS-specific.
